Frequency and distribution of recombination events on chromosome XI and XV.

Recombination events across the genome were determined by counting crossover (CO) and non-crossover gene conversion (NCOGC) events between each adjacent marker. The counts were adjusted for the size of the interval. Dividing the number of COs and NCOGCs for each interval by the expected frequency for the respective event (CO∶6.5/Mb/meiosis, NCOGC: 2.6/Mb/Meiosis) generated a recombination score. CO and NCOGC recombination scores are shown for each interval on chromosome XI (A) and chromosome XV (B). Dashed line indicates the expected frequency if considering a homogeneous distribution ( = 1). Position of the centromere is indicated with (▾).
